好像Python里面有一个wrf.stagger函数,是专门对应这个问题的:
Return the variable on the unstaggered grid.
This function destaggers the variable by taking the average of the values located on either side of the grid box.
Parameters:var (xarray.DataArray or numpy.ndarray) – A variable on a staggered grid.
stagger_dim (int) – The dimension index to destagger. Negative values can be used to choose dimensions referenced from the right hand side (-1 is the rightmost dimension).
meta (bool, optional) – Set to False to disable metadata and return numpy.ndarray instead of xarray.DataArray. Default is False.
Returns:The destaggered variable. If xarray is enabled and the meta parameter is True, then the result will be a xarray.DataArray object. Otherwise, the result will be a numpy.ndarray object with no metadata.
Return type:xarray.DataArray or numpy.ndarray |
